Put up with conclusion to rude shenanigans (7)
I believe the answer is:
endured
'put up with' is the definition.
(I've seen this before)
'conclusion to rude shenanigans' is the wordplay.
'conclusion' becomes 'end' (something's conclusion is its end).
'to' is a charade indicator (letters next to each other).
'shenanigans' indicates anagramming the letters (shenanigans means mischievous behaviour).
'rude' is an anagram of 'ured'.
'end'+'ured'='ENDURED'
(Other definitions for endured that I've seen before include "Bore; put up with" , "Bore or tolerated" , "Patiently suffered" , "Borne" , "Red nude (anag.)" .)
